SHENZHEN — Fitness technology brand Fitkol has announced its latest innovation, the NB Series, a new generation of AI-enhanced treadmills powered by SportMind™, an intelligent real-time training system that adapts workouts based on heart-rate and movement data.
SportMind™ leverages LLM-based analytical intelligence to determine when to increase or reduce training load, maintaining a balanced heart-rate zone and supporting consistent pacing. This greatly simplifies treadmill use, helping users train effectively without frequent manual controls.
The NB Series comprises NB2 and NB6, developed under a human-centric training approach emphasizing comfort, safety and automated exercise guidance. Fitkol kicked off Early Access in late December ahead of the global launch planned for February 2026.
Featuring AI one-touch startup, hands-free voice adjustment, smooth incline control, and a powerful 5.0HP Bosch motor, the NB Series is built for both casual runners and long-distance training.
With a robust running surface and intelligent modulation system, Fitkol aims to offer a treadmill that supports real-world training needs — from beginners building fitness foundations to experienced athletes managing structured endurance programs.
Fitkol states its mission is to ensure running feels easier while keeping training intensity scientifically optimized, and the NB Series reflects that commitment through deep integration of intelligent software with performance-grade hardware.
